If you intend to fish past Sunday, you'll need a new 2021 angling license.
Additionally, the deadline to remove permanent/overnight fish houses is Monday in the southern half of the state. If found unattended over night beyond the deadline, enforcement officials can confiscate the house itself.
Well I sure picked the wrong week to be up at the lake! I certainly enjoy the coldest of days more than this spring weather in February. Seeing the sun is nice, but I'd rather see that at the end of March versus now. What powder there was on the lake is virtually gone. On the plus side, the snow base is solid and good for 4-wheelers as well as sleds. Hopefully we get 6-12" of snow soon and then we will have some great riding conditions. I didn't ride the trails, but did ride quite a bit in the woods. Things are getting bare.
Edit - I just walked outside....it's snowing! I should have complained sooner...
At the risk of sending this thread further off the rails, let's talk "slots".
There is nothing majic about a protected slot limit (PSL). It can be a useful tool if your spawning stock NEEDS some protection, or if there is demand for growing larger fish. All of the lakes you mention have had a PSL in the past, and some still do. The most used PSL originally, protected all fish from 17-26 inches, because that protection covered almost all the mature females in a population (and lots of mature males). The thought at the time was that if some spawners are good, more is better, or at least can't hurt. Wrong!
Almost all those lakes have since adjusted those PSLs, or eliminated them. Red closed the fishery during restoration, then used the PSL while spawning stock still NEEDED some protection. Upper Red has since abandoned the PSL all together for much less restrictive, one over 17", or 20" regulations. Both allow considerable harvest of spawners. The other lakes mentioned have all experienced some stockpiling of excess spawning stock and suppression of new year classes, causing managers to make multiple adjustments to allow more harvest and free up productivity.
Lake of the Woods, which you didn't mention started out with a 19.5-28" PSL to be more compatible with Ontario's regulation (50cm). That worked out well because it allowed considerable harvest under the PSL, reducing spawner density before they grew into the PSL. Finally there's Mille Lacs which has continued with very restrictive harvest regulations, currently with a closed summer season, no PSL, but insted a two inch harvest slot limit. Lot's of large fish, an abundance of spawning stock, but recruitment of new young fish has been dismal.
Now can we get back to discussing why a statewide bag limit reduction applied across all Minnesota walleye lakes, natural or stocked, makes no sense?
